Catalog of Free Database Systems
This document attemts to catalog databases that are
available without payment and with source.
The latest version of the document can be ftp'ed: get
pub/free-databases from ftp.idiom.com. The latest version is
always posted; the ftp version is never ahead.
There is a WWW version provided by Karl Guggisberg of the Software
Composition Group: http://cuiwww.unige.ch/~scg/FreeDB/
I will post this document about once a year to comp.databases,
comp.databases.object, comp.answers, and news.answers. I will also
post it to other groups somewhat randomly.
Please send additions, corrections, and donations to
David Muir Sharnoff <free-databases@idiom.com>
I would like user testimonials. I want to know which databases
are usable and which are trustable! Is there any database on this
list that I could store payroll records on? I have not used any
of these database nor have I used many commercial databases. I am
not qualified to answer your database questions or able to reccomend
a database for your use. Please try not to ask.
Thanks,

description: A major component of the Datascope Seismic Application
Package is a relational database system, Datascope. Although
it is used primarily for seismic applications at the JSPC,
it is a general purpose database system which can also be
useful outside the seismic community. Datascope is a
relational database system in which tables are represented
by fixed-format files. The system provides the standard
operations on relational database tables: subsets, joins,
and sorts. And, since the data is typically plain ascii,
it's also possible to just use standard UNIX tools like
sed, awk, and vi. Some features:
+ It is possible to store ranges as keys and index them
+ Attributes can have units
+ Support for foreign keys
Datascope provides a cheap, easy, fairly intuitive way of
moving from the traditional plethora of formats to a better
approach which organizes the data, documents it, and
provides powerful tools for manipulating it.

name: DiamondBase
version: 0.31
interfaces: C++ library
access methods: b+ tree
multiuser: very limited
transactions: no
distributed: no
query language: C++ methods
limits: limits are set at compile time. The default max records
is 21474836.
robustness: The database engine is quite stable. The multi user
component is a more recent addition, and is still considered
beta. The single user version is separate however and
unaffected.
description: DiamondBase is written entirely in C++, and uses a schema
compiler to generate C++ class defintions for the objects,
as well as some comparison code which is also linked in to
the final executable. Facilities are now available to access
generic relations without providing comparison code. It
was written originally as a replacement for MetalBase which
was too slow. DiamondBase is very fast.

description: Mini SQL or mSQL is a light weight database engine that
supports a significant subset of the ANSI SQL specification
(including joins, ORDERing, DISTINCT, NULL handling, etc).
It is a single proces engine and doesn't use vast amounts of
system resources as other engines can. It supports
client server operations over TCP/IP networks and provides
quite reasonable performance. As an example, on a clunky old
25mhz 386 running Linux (one of the supported platforms) a
sustained rate of 67 inserts per second was achieved
during the insertion of 100,000 table entries.

limits: A single file cannot exceed 4GB.
robustness: The package is quite stable as it is shut down properly. It

description: Typhoon is a relational database management system. It was
originally inspired by Raima's db_VISTA (today Raima Data
Manager) but is relational rather than network based. Typhoon
lacks some of db_VISTA's features, but also contains a number
of nice features not found in db_VISTA.
All relations are defined in a so called Data Definition
Language (ddl) file. You define the database relations like
you would write a C structure with chars, ints, strings,
multidimensional arrays, nested union and structures, etc. Then
you define primary, alternate and foreign keys for each
relation. The Data Definition Language Processor (ddlp)
compiles the database defintion into a binary file which
constitutes the database description. The database relations
are accessed via C subroutines which manipulate individual
records within a table.
- Multiple open database
- Multi-field keys
- Nested structures in records
- Controlled unions
- Referential integrity
- Variable length fields
- Null keys (optional keys in db_VISTA, but easier to use)
- Dynamic opening and closing of database files

interfaces: GNU E, (C++ for direct access to the Storage Manager)
access methods: B+tree and linear-hashing based indexes
multiuser: yes, client-server
transactions: yes, but not nested.
distributed: yes, applications can access multiple servers in a single
transaction. Distributed commits are performed across servers
and clients have access to an interface allowing participation
in distributed commits managed by an external agent.
query language: GNU E -- a persistent programming language based on C++
robustness: High (at least for academic software).
The SM release includes a facility for regression
testing most features, including crash recovery.
description: The EXODUS Storage Manager (SM) is a client-server object
storage system which provides "storage objects" for storing
data, versions of objects, "files" for grouping related storage
objects, and indexes for supporting efficient object access. A
storage object is an uninterpreted container of bytes which can
range in size from a few bytes to hundreds of megabytes. The
Storage Manager provides routines to read, overwrite, and
efficiently grow and shrink objects. In addition, the Storage
Manager provides transactions, lock-based concurrency control,
and log-based recovery.
GNU E is a persistent, object oriented programming language
developed as part of the Exodus project. GNU E extends C++
with the notion of persistent data, program level data objects
that can be transparently used across multiple executions of a
program, or multiple programs, without explicit input and
output operations.
references: A bibliography of EXODUS related papers can be obtained from
the ftp site described below. Some of the papers are available
from the ftp server as technical reports, and are marked as
such in the bibliography.
status: No longer being developed. However, the authors are working
on a new system, SHORE, and will support current Exodus
users well enough to keep them going until SHORE is useable.
GNU E 2.5.8 is in beta and can be ftped.

distributed: no, but maybe later
query language: hypertext-ish X user interface
robustness: The underlaying store handler (NODE) has been used since '89

description: LINCKS is an object-centred multi-user database system
developed for complex information system applications where
editing and browsing of information in the database is of
paramount importance. The focus is on sharing of small
information chunks which combine to make up complex information
objects used by different users for different purposes. The
information chunks are semi-structured in that they contain one
part which is well-structured to facilitate addition of A.I.
processing within the system, and one part which is
unstructured and suitable for management by the user.
Features: shared composite objects, database history,
atlernative views, change collision notification (when more
than one person makes changes to the same composite object)

description: The persistent object management system OBST was developed by
Forschungszentrum Informatik (FZI) as a contribution to the
STONE project (supported by grant no. ITS8902A7 from the BMFT,
i.e. the German Ministry for Research).
OBST was originally designed to serve as the common persistent
object store for the tools of an software engineering
environment.
An essential feature of STONE is that the object oriented
paradigm is pursued consequently as a key concept. OBST is the
common persistent object store for all tools within the STONE
environment.
OBST provides a rich OO model including multiple inheritance,
generics, overloading, and privacy. The schema definition
language is syntactically similar to C++. It comes with a
library of pre-defined classes like Set<Entity>, and
List<Entity>. New methods can be incrementally loaded at
runtime.

description: Texas is a simple, portable, high-performance persistent store

and relies on the underlying virtual memory system for
caching. Texas is easy to use, and is implemented as a UNIX
library. It is small and can be linked into applications. It
requires no special operating system privileges, and
persistence is orthogonal to type---objects may be allocated on
either a conventional transient heap, or on the persistent
heap, as desired. Texas supports simple checkpointing of heap

robustness: The support provided for Triton is limited. As resources
permit, reported bugs will be fixed. Triton is reasonably
robust and has been in daily use in Arcadia for several years
primarily supporting APPL/A and Amadeus.
description: Triton is an object-oriented database management system
designed to support the Arcadia software engineering
environment. It can be used as a general purpose DBMS, although
it has specialized features to support the software process
capabilities in Arcadia in the form of the APPL/A language.
Triton provides for multi-language access and sharing of data,
dynamic creation of classes (with methods) and objects, special
support for relations, and special support for triggers. Triton
uses a client-server architecture with data and methods held in
the server.
Triton is written in E, which is a persistent C++.
What Triton adds to Exodus is another interface and a lot
of higher-level functionality. This includes an Object Manager
shell (catalog, trigger manager, and application objects);
multi-language access and sharing; dynamic definition of
schema and classes; schema catalog; and triggers before and/or
after method invocations.

limits: Will slow down when the database size exceeds
256 megabytes. Otherwise, database size limited
by disk size (up to Macintosh limit, which is,
I believe, 4 gigabytes). Object size limited
to 24 megabytes. If you think of a Wood database
as a random access FASL file, you'll have the
right idea.
robustness: Until it has a real logging/recovery mechanism,
I wouldn't advise using it for mission critical
data. Caches pages in memory, so if you crash,
you will lose. Has a function to flush the
cache to disk, so you can do explicit checkpoints
to make it more robust.
description: Wood is a simple persistent store for MCL 2.0.
This is still alpha software. It is incomplete: though you can
save/restore all Lisp objects to/from a file, there is no

to the Exodus storage manager; however, CORAL can run without
Exodus if disk-resident relations are not required.
A good interface to C++ is provided. Relations defined using
the declarative language can be manipulated from C++ code,
and relations defined using C++ code can be used in declarative
rules. C++ code defining relations can be incrementally loaded.

Guarantees recovery from (almost) all application/system crashes
description: GRAS is a database system which has been designed according
to the requirements resulting from software engineering
applications. Software development environments are composed
of tools which operate on complex, highly structured data.
In order to model such data in a natural way, we have selected
attributed graphs as GRAS' underlying data model.
The current version has programming interfaces for Modula-2 and
C and supports:
- persistent attributed, directed node- and edge-labeled
graphs (including long attributes and indexes)
- temporary/volatile generic sets, binary relations, and lists,
- graph modification triggers causing further modifications
- primitives for version control comprising the capability
for efficiently storing graphs as forward/backward deltas
- primitives for declaring graph schemes and for incremental
evaluation of derived attributes (constraints).
In additon, there are tools for compressing and displaying
graphs. The GRAS system may be considered to be the core of a
graph oriented DBMS environment. The environment is based on a
VHLL called PROGRESS. This environment supports: a
syntax-directed editor for graph schemes, rewrite rules and
sequences of rules; an incremental consistency checker; an
incremental compiler&interpreter for PROGRESS; an enhanced
graph browser

offset to a data file. A library to handle fixed-length records
based on these pointers should be trivial. (Can you say
'dBASEIII'?) Another failing of this library is its total
inability to cope with having several programs modifying
indices at the same time. (it *CAN*, but I won't vouch for the
result) The good solutions to that particular problem are OS

FFW is basically intended to replace similar solutions
based on the Wais search engine, and solves some of the
problems we experienced when using the Wais engine.
FFW supports HTML. It parses input files, ignoring HTML
directives and translating HTML special characters into
ISO8859-1 equivalents.
FFW can build indexes incrementally and can search multiple
indexes at the same time.
Program messages are separated in one file for easy

description: lq-text is a text retrieval package.
That means you can tell it about lots of files, and later you
can ask it questions about them. The questions have to be:
"which files contain this word?" or "which files contain this
phrase?", but this information turns out to be rather useful.
Lqtext has been designed to be reasonably fast. It uses an
inverted index, which is simply a kind of database. This tends
to be smaller than the size of the data, but more than half as
large. You still need to keep the original data.
Lqtext uses dbm (berkeley db or sdbm) to store its indexes.

index size: 5-15% of text being indexed, depending on document size and

requires around 25-30% of original size. Complete retrieval
system requires 30-45% of original text size.
limits: Will probably fail when used with > 4Gb
robustness: It is a research prototype, and as such there are no
guarantees. Don't rely on it as a primary archive tool; but it
is very useful as an adjunct to other storage mechanisms for
e.g. maintaining a personal mail retrieval system. And, of
course, for research purposes.
description: mg compresses and indexes documents and images (indexed by
user-supplied textual description). All components are stored
compressed: text by a word-based method that reduces the space
requiremnent to around 25% of input; images by one of three
different methods (FELICS, Textual Image Compression, two-level
image compression); and index using index compression methods.
The package also includes a mechanism for fast and economical
creation of the index in thge first place. It requires about 8
hours (Sun SPARC 10 Model 512) to compress and index 2 Gb of
text (the TREC collection); final retrieval system requires
about 700 Mb to operate. Multi-term Boolean and ranked queries
are answered within seconds.

description: ciORA is a set of C interface routines to Oracle that are
modeled after the standard I/O portion of the C library. ciORA
presents a familiar interface to an experienced C programmer by
avoiding the awkward embedding of SQL statements using
precompilers and the tedium of using low-level OCI calls.
ciORA eliminates the need for precompilers by supplying an
interface library providing equivalent functions. It also
provides a higher level of abstraction to the functions in the
Oracle Call Interface (OCI). ciORA manages (and hides) the
tedious details necessary when writing programs using OCI by
replacing the cumbersome Oracle constructs such as logon data
areas, cursor data areas, and external datatypes, the Oracle
array interface, bind variables, select-list-items, and the
like with constructs familiar to a C programmer using the
standard I/O portion of the C library. ciORA also provides a
consistent interface to Oracle errors similar to the convention
used in C's errno.

perceived need at Genentech to provide graphical front-ends on
Macintosh computers to Informix relational databases running on
Unix servers. DSQL version 3 is distributed with 2 server
implementations and four client library implementations. The
API for the client libraries has been standardized, and the
client code is divided into portable and architecture-specific
portions.

Snodgrass and Andreas Steiner.
TimeDB runs as a frontend to the commercial (relational)
database system Oracle. ATSQL2 statements (queries, updates,
and assertions) are compiled into (sequences of) SQL-92
statements which are executed by the backend. TimeDB provides
bitemporal statements. It excels in a seamless integration
of time into databases by supporting upwards compatibility and
temporal upwards compatibility. Implementation is continuing.
A SQL main memory interpreter is shipped with this release,
such that TimeDB can be run without Oracle.

description: AdaSAGE is not a DBMS.
AdaSAGE is an application development tool that provides
facilities for creating an application specific relational data
base. There are two aspects of SQL dialog to consider. First is
listening to SQL and responding by executing the requested
command. Second is issuing SQL to get a foreign system to
execute some process on your behalf. In the first case AdaSAGE
provides both an embedded SQL technology and an interactive SQL
system adapted to comply with ANSI-SQL DML Level 1. In the
second case AdaSAGE does not provide any capabilities for
creating SQL commands, but since AdaSAGE is a set of Ada
packages there is no reason that a package could not be
developed to do so.
The capability to record all transactions and roll forward from
previous dates gives an audit trail and recover capability.
These features are often provided within data base management
systems, and are provided with AdaSAGE as a logging option, but
seldom if ever are they used in final applications because of
the excessive time and data storage requirements.

description: MultiCal is both a novel approach to supporting multiple
calendars and internationalization of time constants and a
query processor prototype that demonstrates this approach.
MultiCal consists of about 48K source lines of C code; the
query processor prototype consists of about 63K source lines of
code. The documentation consists of fifteen documents,
comprising some 300 pages of material.
MultiCal consists of an approach to providing limited
extensibility for support of multiple calendars and languages
for temporal support within a database management system
(DBMS). We have augmented the Structured Query Language (SQL),
specifically, SQL2, with time values, i.e., temporal
constants. Our approach is notable in that we allow many
different calendars to be used in the database management
system, and we incorporate only calendar-independent constructs
into the language. We introduce three new temporal data types.
New language features are defined for temporal built-in
functions, special time values, arithmetic expressions
involving time, temporal predicates, and aggregate functions
over time. Ten languages are supported.
To illustrate how an existing DBMS could be augmented to
support multiple calendars, we provide a prototype DBMS that
supports the proposed extensions. This prototype consists of
query analysis and execution components. It eschews traditional
functionality such as concurrency control and disk access
methods, as these aspects are not relevant to timestamp
management.
